Server migration

Since two days, I have merged the main servers used by two research laboratories at work. One server was an old Linux server which really needed a hardware upgrade, and the other one was a Mac Pro machine running a flaky OS X Leopard. The new server is of course running Linux: Debian Lenny.

It was a very interesting experience: working out procedures to migrate the mailboxes (from Dovecot on the Linux server and Cyrus on the Mac server to Cyrus on the new server), finding out how to set up one NIC in two different subnets (especially the routing is a little bit tricky), getting all services hooked up to LDAP and managed by GOSA, getting dhcpd to do exactly what we want in a shared-network set up, and much more.

The new server is a HP DL185 G5 with an AMD Opteron quad core CPU and 8 GB of RAM and hosts two KVM virtual machines, one for public services and another one running internal services. You can visit the two websites, which are also hosted on this machine of course, of the concerned research labs:

Maybe in the not too far away future, I should try to move the services hosted on the underpowered desktop machine running this website, also to a virtual machine…
